Patent Number: 6,251,115

Title: Method for the medical treatment of the neurological system

Abstract: A medical positioning device internal to a catheter or lead for the nonlinear insertion of a catheter or lead into an interior organ. The medical positioning device comprising an outer tubular member, a superelastic inner tubular member having a curvature positioned within the outer tubular member, and an innermost member positioned within the inner tubular member. The superelastic inner tubular member straightens when placed substantially within the outer tubular member and the inner tubular member resumes its original curvature and moves along a curvilinear trajectory when advanced outwardly from the outer tubular member. Insertion of the outer tubular member into the body, advancement of the inner tubular member into an interior organ, and advancement of the innermost member guides and positions a catheter or lead into an interior organ and to a treatment site along a nonlinear insertion path.
